At a glance
Robot vacuums range widely in price. The jump in quality comes mostly from navigation and the dock.
Navigation
- Lidar: spinning laser maps rooms accurately, works in the dark.
- Camera (vSLAM): can recognise obstacles like cords and pet waste on better models; needs light.
- Bump-and-go: cheapest, random paths, no room-by-room control.
Is a self-emptying dock worth it?
If you have pets or want to go weeks without touching it, yes. It adds cost and ongoing bag purchases.
Mopping
Mop-combo robots are good for light daily maintenance, not deep cleaning. Look for mop lifting if you have rugs.
Running costs
Budget for filters, brushes, bags and mop pads. Check that replacement parts are easy to buy.
What to evaluate before you spend
- Navigation type (lidar, camera, bump). Write this down before you compare options, and reject anything that hides the detail.
- Obstacle avoidance for cords and pet mess. If two options tie elsewhere, this criterion usually breaks the tie.
- Self-empty dock and bag costs. Note the current number or policy; marketing blurbs go stale fast.
- Mopping capability. If two options tie elsewhere, this criterion usually breaks the tie.
- Carpet performance. Write this down before you compare options, and reject anything that hides the detail.
- App mapping and no-go zones. Treat this as a hard filter: if a page is vague here, move on.
